Thanks, yes, this workaround works okay.
Still I am wondering why such a workaround is needed at all.
The NodeClick-event should not be fired when nodes are just expanded/collapsed.
I have another VirtualTreeView instance where clicking on a node
just selects this node (which VTV does internally).
Interestingly, in this case I can collapse/expand without VTV selecting the
node.
Only if I use the NodeClick-event it is fired together with expand/collapse.
IMO this is a bug.
